COM BINED AGITATOR AND CONVEYER.

SPECIFICATION forming part of Letters Patent No. 409,816, dated August27, 1889.

Application filed January 16, 1889. Serial No. 296,481. (No model.)

To all whom it may concern.-

Be it known that I, VALERIUS D. ANDER- sON, a citizen of the UnitedStates, residing at Cleveland, in the county of Guyahoga and State ofOhio, have invented certain new and useful Improvements in Conveyers forDriers, Rendering-Tanks, &c., of which the following is a specification.

My invention relates to rendei'ingtanks, driers, and like structures;and it consists in the combination therewith of a wing, blade, or flight(one or more) so applied to the rotating drum or cylinder, or to itsshaft, that rotation in 'one direction shall cause it to as sume aposition parallel to the axis of the drum or cylinder, and that rotationin the reverse direction shall cause it to assume a position oblique tothe axis of the cylinder, so that in one position it shall serve simplyto lift the material and turn it over or to agitate it, while in theother position it shall serve to move the material toward a dischargeopening or outlet.

In the annexed drawings, Figure 1 is a perspective View, and Fig. 2 atop edge view, of a conveyer blade or flight arranged in accordance withmy invention.

A indicates the body or shell of the tank or chamber in which theconveyor is to be used; 13, the shaft thereof, and C theconveyer-blades. These may be pivotally attached at one end either toradial arms D, extending from the shaft at suitable intervals, or toradial stems or posts D, secured to the interior of the shell A, asshown in both forms in Fig. 1. Assuming the shell A thus provided to beturned in the direction indicated by arrow in Fig. 1, it will beapparent that the material lying on the under side of the shell willoffer a resistance to the advance of the flights or blades 0, which willthus swing back until prevented from moving farther by coming intocontact with the wall of the shell or with a fixed stop provided tolimit such play, while if the direct-ion of rotation be reversed theblade will swing in the opposite direction until similarly stopped.

To actually limit and determine the position of the blade or flight ineach case,I provide two fixed stops a and b, the former in such positionas to hold the blade or flight in alignment with the axis of shaft A andthe other permitting it to assume such angle or inclination relativelyto the axis of the shaft as will cause it to advance the material towardthe discharge end of the cylinder or toward a discharge-outlet at anysuitable point in the length of the cylinder. It is manifest that theprecise form of the stop and the manner of hingin g, pivoting, ormounting the blades or flights is wholly immaterial, provided only thatwhen subjected to the resistance of the material they shall, underrotation in one direction, assume a position parallel to the axis of theshaft, and under rotation in the opposite direction assume apositionoblique to or out of line with said axis.

Having thus described my invention, What I claim is 1. In combinationwith a tank or cylinder, a loosely-pivoted flight and stops to limit themovement of said flight, said stops being located in such positions thatwhen arrested by one the flight shall be held in alignment with,

and when arrested by the other it shall be oblique to, the axis of thecylinder.

2. In combination with a cylinder and with a post or arm D, a blade orflight O, pivotally attached to said post or arm and free to swing aboutits pivot when in operative adjustment, and stops (4 and Z), serving tolimit the play of the free end of the blade or flight in oppositedirections.

In witness whereof I hereunto set my hand in the presence of twowitnesses.

VALERIUS D. ANDERSON.
